Blower Door Test in Guttenberg, NJ

How Is A Blower Door Test Conducted?

During blower door test in Guttenberg, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.
